摘要
氢能因其经济﹑可持续生产的优势逐渐成为不可替代的清洁能源,本实验采用新型生物制氢反应器-厌氧折流板反应器,以蔗糖废水为底物进行了为期40天的运行研究,在降解有机废水的同时制得了可利用的氢气,为实际应用提供了较有价值的参考。在低有机负荷条件下成功启动反应器后,在(35±1)℃的温度下,控制进水pH值在6.9±0.1范围内,分阶段提升进水有机负荷,在进水COD为5599mg/L时,反应器总COD去除率达到最高,峰值为58.99%;当进水COD提升至6136mg/L时,单日产氢量达到最高值为35.22L/d。总体来看,反应器运行情况良好,最佳进水COD值在6136mg/L,此时系统产氢效果最佳且COD去除率较峰值相差不大。
Hydrogen energy has gradually become an irreplaceable clean energy because of its advantages of economic and sustainable production.In this experiment,a new type of biological hydrogen production reactor,anaerobically baffle reactor,was used to study the operation of sucrose waste water for 40 days.The available hydrogen was prepared while the organic waste water was degraded,which provided a valuable reference for practical application.After successfully starting the reactor under the condition of low organic load,at the temperature of(35±1)℃,the pH value was controlled in the range of 6.9±0.1,and the organic load was increased in stages.When the COD was 5599mg/L,the total COD of the reactor was removed.The removal rate reached the highest,the peak value was 58.99%,and when the COD increased to 6136mg/L,the daily hydrogen production reached the highest value of 35.22 L·d.In general,the operation of the reactor is good,and the optimal COD value is 6136mg/L.At this time,the hydrogen-producing effect of the system is the best and the COD removal rate is less than the peak value.
